Bug: Switch chain ID

[mrosendin]

Describe the bug

Unable to switch chain ID using wagmi's useSwitchNetwork

Steps

1. Set up config like in the wagmi connector docs example with base and baseSepolia chains*
2. Connect wallet as shown in the docs example
3. Call switchChain to baseSepolia.id (assuming we are connected to base mainnet)
4. Log chainId in the console using useChainId hook to confirm chain ID has not switched.

I've created a reproducible example here: https://github.com/mrosendin/smart-wallet-expo-switchChain

---

*I've installed client v0.1.1 and wagmi-connectors v1.0.0 and appChainIds property in the metadata object for createConnectorFromWallet is not recognized, so I removed it. Here's the error message:

Object literal may only specify known properties, and 'appChains' does not exist in type 'StrictOmit<AppMetadata, "appChainIds">'.

This error msg is at odds with the docs example.

Expected behavior

Connector switches chain and useChainId returns the updated chain ID.

The chain ID will switch only after a hard refresh in Expo Go

Version

client v0.1.1, wagmi-connectors v1.0.0

Workaround
Force a wagmi reconnection when the switch doesn't auto-detect:

import { useReconnect } from "wagmi";

const { reconnect } = useReconnect();
const { connector } = useAccount();

// After switchChainAsync succeeds, set a short timeout to force sync
setTimeout(async () => {
  if (wagmiStillOutOfSync) {
    await reconnect({ connectors: [connector] });
  }
}, 2000);
